    This report describes the test result of jet discharge of saturated water through a 4-inch discharge pipe from a pressure vessel with 4m3 of inner volume, under the initial condition that the pressure was 69kg/cmcm2·g, temperature was 283°C in the pressure vesse1. Behind the exit, a 10 ton load cell was installed to measure the thrust force due to the sudden jet discharge. In front of the pipe exit the target disk of 1, 000mm diameter was insta11ed. The distance between the pipe and the target was 500mm. Thirteen pressure transducers and 13 thermocouples were mounted on the target disk to measure the pressure and temperature increase due to jet impingement on the target.
    The following conclusions are obtained:
    (1) Pipe reaction thrust is calculated using homogeneous flow model at the early stage of the blowdown where the stagnation quality is low, The computed value gives good agreements with the experimental data.
    (2) The maximum pressure on the target due to jet impingement is 1kg/cmcm2·g when the distance between the pipe exit and the target is 500mm.
    (3) Mass flow rate was obtained by RELAP4/MOD5. The agreement between calculational and experimental results was given under the condition that Cd=0.63 for a 4-inch discharge pipe.

    The helium engineering demonstration loop (HENDEL) consists of the first and second helium loops (M1 and M2 loops), adapter helium loop (A loop) and six test sections, the first of which was completed and the others to be designed.
    This report describes operational data of components (heater, blower and cooler) and overall performance of the second helium loop (M2 loop) and adapter helium loop (A loop), during the test operation until March 1983.
    Finally M2 and A loops were confirmed to be able to provide helium gas up to 1, 000°C, 4.0kg/s and 4.0MPa to the in-core structure test section (T2) and the others which are to be installed.

    A new X-ray CT scanner system, using time-averaged projection data (X-ray beam intensity), called Advanced Computed Tomography System (ACTS), was developed for measuring accurately the local void fraction distribution in the two-phase flow of various flow configurations and patterns.
    A horizontal circular tube and a 4×4 rod bundle were used as test sections. Air-water mixtures were used as test fluids. The local void distribution measured by ACTS and that measured by an impedance probe were compared. The agreement was excellent for tested flow patterns (bubbly flow, slug flow, plug flow and annular flow) both in the horizontal tube and in the 4×4 rod bundle. It was concluded that ACTS can be applied to the measurement of local void distribution in any flow patterns and in any flow channel configurations.
